s3c_rtc_enable/disable_clk() functions were designed to be called multiple
times without reference counting, because they were initially only used in
alarm setting/clearing functions, which can be called both when alarm is
already set or not. Later however, calls to those functions have been added to
other places in the driver - like time and /proc reading callbacks, what
results in broken alarm if any of such events happens after the alarm has
been set. Fix this by simplifying s3c_rtc_enable/disable_clk() functions
to rely on proper reference counting in clock core and move alarm enable
counter to s3c_rtc_setaie() function.

(RTC,ALM)YEAR registers of Exynos built-in RTC device contains 3 BCD
characters. s3c-rtc driver uses only 2 lower of them and supports years
from 2000..2099 range. The third BCD value is typically set to 0, but it
looks that handling of it is broken in the hardware. It sometimes
defaults to a random (even non-BCD) value. This is not an issue
for handling RTCYEAR register, because bcd2bin() properly handles only
8bit values (2 BCD characters, the third one is skipped). The problem
is however with ALMYEAR register and proper RTC alarm operation. When
YEAREN bit is set for the configured alarm, RTC hardware triggers alarm
only when ALMYEAR and RTCYEAR matches. This usually doesn't happen
because of the random noise on the third BCD character.
Fix this by simply skipping setting ALMYEAR register in alarm
configuration. This workaround fixes broken alarm operation on Exynos
built-in rtc device. My tests revealed that the issue happens on the
following Exynos series: 3250, 4210, 4412, 5250 and 5410.

As per code flow s3c_rtc_setfreq() will get called with rtc clock disabled
and in set_freq we perform h/w registers read/write, which results in a
kernel crash on exynos7 platform while probing rtc driver.
Below is code flow:
s3c_rtc_probe()
clk_prepare_enable(info->rtc_clk) // rtc clock enabled
s3c_rtc_gettime() // will enable clk if not done, and disable it upon exit
s3c_rtc_setfreq() //then this will be called with clk disabled
This patch take cares of such issue by adding s3c_rtc_{enable/disable}_clk in
s3c_rtc_setfreq().

Commit df9e26d093 ("rtc: s3c: add support for RTC of Exynos3250 SoC")
added an "rtc_src" DT property to specify the clock used as a source to
the S3C real-time clock.
Not all SoCs needs this so commit eaf3a65908 ("drivers/rtc/rtc-s3c.c:
fix initialization failure without rtc source clock") changed to check
the struct s3c_rtc_data .needs_src_clk to conditionally grab the clock.
But that commit didn't update the data for each IP version so the RTC
broke on the boards that needs a source clock. This is the case of at
least Exynos5250 and Exynos5440 which uses the s3c6410 RTC IP block.
This commit fixes the S3C rtc on the Exynos5250 Snow and Exynos5420
Peach Pit and Pi Chromebooks.
